Last I checked the web page, there were still some classes that were not full. In addition to classes, there will be special presentations .... display room.... local tours.... vendors.... lace contest .... tat off.... teacher showcase.... sounds like a wonderful week.

On Wednesday, the sales room, display room and special evening
presentations are open to the public free of charge. In addition a
Mini-Registration, which is available for any one day of the convention,
permits the registrant to attend that day’s sponsored activities.
See Registration information for details about a Mini-Registration.
On Saturday there are classes. The Display Room will not be open,
but the Sales Room will be open to the public at no cost."
